While Pennsylvania legislators are gearing up to take a crack at reworking the state’s Megan’s law, one prosecutor is working on an appeal to the U.S. Supreme Court challenging one of the state Supreme Court’s recent decisions shooting down parts of the statute’s sexually violent predator provisions.

Erie County District Attorney Joseph P. Conti said he and his staff are preparing an appeal to the highest court in the nation. He said he will file the appeal in Commonwealth v. Williams by the end of the month.
